Bungie Plans to Restore Destiny 2's Vaulted Content

Bungie has announced plans to return to Destiny 2 and re-add content that was previously vaulted, framing it as the foundation for new Destiny stories and future games.

For long-time Guardians, that means campaigns, raids and dungeons that disappeared could become playable again — and for returning or newer players, a much larger pool of endgame content to learn.

If older raids and dungeons come back, demand for mechanics coaching on those encounters tends to spike, because most players never cleared them the first time around.

• Vaulted campaigns, raids and dungeons may return over time.
• Great news for new and returning players building their endgame knowledge.
• We'll keep this guide updated as Bungie confirms specifics.
